We look at the division of 964570 by 86 
Let's see how many times 86 fits into 964570.

Advancing to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 86

Moving on to step 2:
96 divided by 86 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 86 away from 96, we end up with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 86

Going ahead to step 3:
86 can be fit into 104 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 86 from 104 and we're left with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 86

Moving on to step 4:
86 can be fit into 185 2 times, resulting in a remainder of 13.
The next digit of our result is 2. 
Result so far: 112.0
Deduct 172 from 185 and we're left with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 86

On to step 5:
86 goes into 137 1 times with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1121.0
Subtracting 86 from 137 leaves us with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 86

Going ahead to step 6:
86 can be fit into 510 5 times, resulting in a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 11215.0
Deduct 430 from 510 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 7:
86 can be fit into 800 9 times, resulting in a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 11215.9
Subtracting 774 from 800 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
86 can be fit into 260 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 11215.93
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11215.93
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 86 fits into 200 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 11215.9302
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
280 divided by 86 is 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 11215.93023
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
When dividing 220 by 86, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 11215.930232
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
86 goes into 480 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11215.9302325
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
500 divided by 86 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 11215.93023255
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 11215.93023255 and a remainder of 7e-08.
